[dtp-dev] NoClassDefFoundError though plugin is loaded

[Anil T Samuel <anil.samuel@xxxxxxxxxx>]

Hi

I have 2 plugins - oracle.dbtools.connectivity and 
oracle.dbtools.modelbase. When a class in oracle.dbtools.connectivity 
that inherits from oracle.dbtools.modelbase class it is resulting 
NoClassDefFoundError during its instantiation.

I checked the plugins to make sure that the classes are in there. Also 
the Help->About Eclipse->Plug-in Details lists both plugins. This error 
message is found in the .metadata/.plugins/org.eclipse.ui.workbench/log.

Any suggestions ?

Regards
Anthos
